THE EFFECT OF BICARBONATE SODA ON THE PHYSICAL PROPERTIES OF A BAKED CUP CAKE
Introduction
Atoms are the building blocks for all living and non-living substances. All atoms of form a chemical element and when these elements are put together, in countless combinations, these atoms give all known forms of matter. Molecules are groups of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction. A compound is a substance that is formed with two of more atoms that a chemically bonded together. A mixture is a substance that is made up of two substances but the substances are not chemically bound.
Chemical and physical changes happen constantly in everyday life for example cooking. A physical change takes place without any molecular composition change. In physical changes the element or compound is present before and after the change as happened. Physical changes involve a change in a measure of a physical property. Some physical properties are appearance, texture, colour, odour, melting point, boiling point, density and solubility. Physical changes do not change the molecular composition while chemical changes do. Therefore different elements or compounds are present at the end of the chemical change. This is because the atoms in the compounds are rearranged to make different compounds. Consequently, the element and/or compounds at the start will be always be different or altered at the end of the…
